The HR Banjo LSD centre in the old girl isn't sounding so good under load, so I am looking at options before I start pulling things apart.
Is it more cost effective to sort out the LSD or should I opt for a Trutrac?

I don't go to drags or anything like that, just the odd "spirited" acceleration from the lights etc.

I've got a rebuilt HR LSD in the FB (yet to drive it in anger), and a trutrac in the BW78 in my EK wagon (which gets leaned on a lot at Eastern Creek).

The banjo tru-trac will set you back about $1600. Depending on whether what you find is repairable or not, you could be facing close to that much to have the HR centre rebuilt. That sounds sad, but from the diff work I have had done is not too far from the truth.

You will never kill the trutrac, but will be rebuilding the HR periodically.

The trutracs are a nice centre, but you would soon find the next weakness (coarse spline axles) if you wanted to lean on it. Probably not an issue unless you take it to the strip.

Cheers,

Harv's advice matches my expereince - not so much with HR diffs though. My experience is with the VY centre the upgrade was around the same price as the repair. Fortunately I had the tru-trac with the roller I purchased with the insurance $ post a collision with a roo. Enough to write off the SS ute so had to do the swap from one chassis to another and upgraded the diff while I was at it.
